If you would like to get
'fit', perhaps the best course of action is to go down to
the local gym and book yourself in for a fitness assessment
and have them put you on a fitness program which is tailored
specifically to the needs of your sport. If you are seriously
out of shape, the first stage is to lay off the beef burgers
and then see your doctor to make sure your heart, lungs
and other internals are up to the job.
You may do yourself a BIG
favour at this point by being brutally honest with yourself.
Better still, get a friend/partner to give you an honest
opinion of your health state. Research has shown that most
of us regularly over-estimate how fit we are and how much
real physical activity we do.
